get your reservations NOW if you can. there are 3 campgrounds that are sort of off the main track.
1. bluebell is a few miles south of highway 16 on the state park scenic loop.
2. stockade lake south is back off the highway at the back of the lake.
3. sylvan lake is up on the north end of the park.
the others are strung along highway 16.
all of the campgrounds are nice, all have some shade or a lot of shade, all have some elec sites and water and bathrooms. Game Lodge is the only one with a dump station.
good luck, hope you can get a reservation.
